Heater not working

The heater in my 06' 2500 cummins has quit working. All the functions seem to work except it will not blow warm air, only cold. Could it be possible for no coolant to be going through the heater core?

I don't know what years had the blend door issue, but yours should be covered under warrany. Also, check the temp gauge- if it's not getting up to temp you could have a bad thermostat.
